First off, where and how are you mounting it?

nvme0n1 is where my main system is, nvme1n1 and nvme 2n1 are mounted but i cant make changes, and when i click properties, it says only root has permission.

I used sudo chown maru:maru /dev/nvme2n1 but i still cant use the ssd as a user

Why do you want your user to own the device?
If you just want your user to own the mounted directory, chown that after mounting the device

sudo chown -R maru:maru /run/media/maru/51b6a792-d1d8-4f1b-a5bb-a54399b92337

will own everything in there to the user maru.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Also read the wiki a bit. Start here.

You're supposed to know stuff like this…

But, I am puzzled that Dolphin created the mountpoint in /run/media/maru/ without those permissions.

seth · 2022-07-17 19:55:51

It's not the mountpoint but the (root if the) mounted filesystem.

ewaller · 2022-07-17 20:56:26

Well, heck. In all these years, I never realized the root of a file system carried permissions. The model I had had in my head was that that file systems were intrinsically owned by root and adopted the permissions of where they were mounted. I read your assertion, and was sure you were wrong -- so I had to go off and prove myself wrong.

Thank you.

Perhaps rooted in the pattern that mounting FAT32 and other non-filesystems will frequently get you the "ownership" of the mounting UID for the entire non-filesystem.
Lennart would have less issues w/ his homed, though, if it was the case
(No chown() based uid mapping…)

To understand why that approach would lead to problems

cd tmp
mkdir foo
sudo touch foo/bar
ls -la foo # so far so good
rm -f foo/bar # no sudo here
ls -la foo # errrrr … ewww

I read your assertion, and was sure you were wrong -- so I had to go off and prove myself wrong.

Testing a firm belief probably says something very admirable about your character - but since I'm an arrogant jerk, I'll just take it as a compliment and thank you as well
